I'm not experienced enough to really answer that, but for that number, I'd run with a VPN - if that's all you're going need - but if you grow?
Also, a tool like No Hands Proxies [thread here on BHW], will let you scrape public proxies and with the click of a button assign a proxy to your system.
Just my thoughts, hopefully someone more experienced with chip in.
[ps. I'm not affiliated with any tool mentioned above - but do use it]
